Referring now to "the drawing in detail 1 wherein likenumerals ,of reference indicate corresponding parts throughout the several I I Views, the description will first be confined to the showing of Figures1,i2 and 3; and there is indicated by the numeral 1, mold he invention be" thus? understood the accompanying drawingsforming a part of this specification withthe understandingthat theinvention is notconfined to any strict conformity with the-showing; of the drawnonnnsomlorennnn sauna, 'rExAs.-,

further having formed transversely there-J ber 11 having formed along one side at the through adjacent each end thereof aver tical series of apertures 13. shown in Figure3 the head member 11 extends longitudinally of the foot 5 and the neck 9 joins the head at approximately the a central part thereof. I

-The foot has the toe portion towards the As clearly end detachably held thereto by "rivets or other appropriate means as indicated at15 so that this-toe may be become badly worn.

replaced when it has i when the subsoiler just described is placed in position upon the middle breaker the face'16 of the head ll is placed against the side of the rudder 4 theflange 12 overlying the top edge of-the rudder'aszshown in the-sectional View in Figure 2. The apertures' l3 in the head are then alined with the apertures formed in the rudder l and a securing bolt 17 is then passed through the head and the rudder to maintain the sub-I soiler inposition thereon. v

It will be seen, that the foot can be adjusted verticallybeneath. theplowsis'o that the groun'd maybe worked a slight distance 70 h, "side of this foot issIightIy. concaVe-asfindi'-;
